Battery - Electronic Drains Which Shut Off When the Battery Cable is Disconnected Test

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

Repeat the steps of the battery drain testing.
Make sure all the doors are closed and all accessories are off. Without starting the engine, turn the key to ON for a moment, then OFF. Wait a few minutes for the illuminated entry lamps to turn off, if equipped.
Connect the ammeter and read the amperage draw.

The current reading (current drain) should be less than 50 mA (0.05 amp). If the current drain exceeds 50 mA (0.050 amp) after a few minutes, and if this drain did not show in previous tests, the drain is most likely caused by an inoperative electronic component. As in previous tests, remove the fuses from the BJB or CJB one at a time to locate the problem circuit.
